ABSTRACT:
A pair of dies is disclosed for attaching a surgical needle having a generally cylindrical end portion defining an elongated aperture having a generally circular cross-section and a suture having a generally elongated end portion of generally circular cross-section corresponding in dimension to the elongated aperture of the first needle. Each die has a pair of extensions spaced apart from each other and defines a generally circular crimping surface portion corresponding in dimension and configuration to the generally cylindrical outer surface portion of the needle. The space defines a unique relief zone between the pair of extensions of the die and is of configuration and dimension sufficient such that when the suture is positioned within the aperture of the needle and the dies are respectively positioned about the corresponding portion of the needle, the application of impact force to the dies will cause crimping of the needle with respect to the suture so as to attach the suture and the needle while portions of material forming part of the needle adjacent the stricken area are permitted to be deformed and to collect within the relief zones defined between the pairs of arcuate surface portions. Generally arcuate die overlap portions may be optionally provided on each die. A method of attaching a surgical needle to a suture is also disclosed.
